This Baby Lock Serger works like a dream and came with the original manual and a Creative Serging book! I have a great Serger, but, one can always use a back up! This one is pretty old, but it does have differential feed. I have seen it for sale for at least $100, so $14 was a good deal! This one will be available for my students to use during our lessons. I guess, I need to begin a fourth cover!
